Well for a first time gun (for a first time owner). What more would I have to do besides home defense, range shooting, cww/open carry and the odd competition? I'm building an ar15 (because I'm a cheap fuck and building this is fun) at the moment because I want a rifle that can do anything (home defense, range, hunting, target shooting) and then specialize when I find something I like, although sights are still something I can't find what I like yet for my rifle.
You misunderstand
> home defense
You'd typically want something with modularity that can take an optic and a light. G19 works fine for that tbh
> range shooting
For a range gun, you'd want something with a much nicer SAO trigger like a 1911 or Jericho 941/CZ75, or something more interesting or historical. Those guns however are big, SAO, and dont conceal well
> CCW
If you want to conceal carry, a smaller subcompact gun may be more desireable, such as a S&W bodyguard or Glock 42/43/43x, but those guns have less support and being smaller aren't as nice to shoot.
> competition
For competition you'd want a gun built for competition, like a competition built Glock 17, CZ SP01, 1911, etc. Those however are very large guns and their features do not lend to durability, reliability with hollow points, or concealability
For each of the things you want to do, a different gun would serve you better in that endeavor,
however, a glock 19 will be plenty serviceable in all those roles, where some of those other guns would do very poorly in another role (I dont care what the fudds say, a 1911 is a terrible CCW gun).
